Abstract
The invention discloses a wheel-side speed reducer of a mining truck. The wheel-side speed reducer of the mining truck comprises a planet carrier, a half axle is arranged in the center of the planet carrier, a sun gear is arranged on the half axle, three hinge pins which are fixed with the planet carrier are arranged on the periphery of the sun gear, and the hinge pins are connected with a planet gear through cylindrical roller bearings. According to the wheel-side speed reducer of the mining truck, the cylindrical roller bearings are additionally arranged between the planet gear and the hinge pins, and the overall load capacity is enhanced; meanwhile, the hinge pins and the planet carrier do not need to be replaced during maintenance, and convenience and rapidness are achieved.
Description
Technical field
The present invention relates to mine truck accessory technical field, particularly a kind of mine truck wheel reductor.
Background technique
The original-pack wheel reductor of TR50 (TEREX3307) mine truck forms primarily of semiaxis, sun gear, bolt, briquetting, bearing pin, packing ring, needle bearing, planetary pinion and planet carrier.Because China's mine operation condition is special, road conditions is severe, and overloading is serious, the bearing capacity of its needle bearing is transfinited and is in overload operation situation for a long time, serious reduce needle bearing working life and cause the damage of wheel reductor.
Summary of the invention
The object of the invention is to overcome or slow down the part at least above-mentioned shortcoming, a kind of mine truck wheel reductor is provided hereby, comprise planet carrier, the center of described planet carrier is provided with semiaxis, described semiaxis is provided with sun gear, it is characterized in that, all sides of described sun gear are provided with three bearing pins fixed with planet carrier, and described bearing pin connects planetary pinion by roller bearing.
Preferably, the other end of described semiaxis opposing rows carrier is provided with platen, and described platen compresses described bearing pin in the end face of planet carrier.
Preferably, described bearing pin is axially connected with at least two roller bearings along it, is provided with back-up ring between adjacent described roller bearing.
Preferably, packing ring is provided with between the inner ring of described roller bearing and planet carrier.
Preferably, inside diameter ranges 2.35 ＂ ~ 2.6 ＂ of described roller bearing, its external diametrical extent 5.1 ＂ ~ 5.95 ＂, its width range 1.18 ＂ ~ 1.81 ＂.
The present invention is intended to, and sets up roller bearing between planetary pinion and bearing pin, strengthens overall load capacity; Simultaneously when keeping in repair without the need to changing bearing pin and planet carrier, more convenient.
Accompanying drawing explanation
Describe these and other aspect of the present invention in further detail now with reference to appended accompanying drawing, it is depicted as currently preferred embodiment of the present invention.Wherein:
Fig. 1 is the structural representation of the present embodiment.
In figure: 1, planet carrier; 2, semiaxis; 3, bearing pin; 4, roller bearing; 5, planetary pinion; 6, platen; 7, sun gear; 8, packing ring; 9, back-up ring.
Embodiment
Below in conjunction with accompanying drawing and instantiation, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 1, a kind of mine truck wheel reductor, comprises planet carrier 1, the center of planet carrier 1 is fixed with semiaxis 2, semiaxis 2 is provided with sun gear 7, and all sides of sun gear 7 are provided with three bearing pins 3 fixed with planet carrier 1, and bearing pin 3 connects planetary pinion 5 by roller bearing 4.
Use the roller of roller bearing 4 and raceway to be linear contact lay due to the present embodiment or repair lower linear contact lay, radial bearing capacity is large, is applicable to bear heavy load and impact load; In addition, its inner ring or outer ring separable, be convenient to installation and removal.
Due to wheel reductor in use, very easily occur damage, then need to carry out periodic maintenance and repairing to it.And the maintenance difficult point of wheel reductor is, when carrying out maintenance to planetary pinion 5 or changing, need bearing pin 3 is separated with planet carrier 1, very not easily.So, for making the mine truck wheel reductor of the present embodiment more be convenient to dismounting, be provided with platen 6 at the other end of semiaxis 2 opposing rows carrier 1, platen 6 compresses bearing pin 3 in the end face of planet carrier 1.
Further, bearing pin 3 is axially connected with two roller bearings 4 along it, is provided with back-up ring 9 between adjacent roller bearing 4.
So, the present embodiment, by the design by two roller bearings 4, can provide larger load capacity for the automobile travelled in mining area, be applicable to this type of severe running environment.
Because automobile jolts back and forth in the running process of mining area, constantly can collide between the roller bearing 4 of its wheel reductor and planet carrier 1, cause and damage or skew is installed, affect working life.Then the present embodiment is provided with packing ring 8 between the inner ring and planet carrier 1 of roller bearing 4, slows down the impact of automobile bumpiness traveling on wheel reductor to reach.
In addition, the roller bearing 4 of the present embodiment is mainly used for TR50 (TEREX3307) mine truck, then in order to coordinate the use size of TR50 (TEREX3307) mine truck, the roller bearing 4 of inside diameter ranges 2.35 ＂ ~ 2.6 ＂, external diametrical extent 5.1 ＂ ~ 5.95 ＂ and width range 1.18 ＂ ~ 1.81 ＂ is selected to be advisable.
